To all QUZLOWIZZ? mag concern: I I

.Be it known that I, HENRY F. BJ'J HMAN, a'citizen'of the United States,residingat Battle Creek, in the county of Calhoun and State of Michigan,have invented certain new and useful Improvements in FeedinglVebs toPrinting-Presses; and "I hereby; declare that the following is a" full,clear, and exact description thereof, reference being had to theaccompanying drawings, which form part of this specification, .l

This invention relates to rotary web print'- mg presses and hasparticular reference to the type of single page tubular plate print ingpresses shown in myPatent No. 867,230 of1907, but is applicable to anyweb printing presses using narrow two page long plate cylinders, andrequiring a multiple of perfecting mechanisms to producealarg'ernumber'of pages.v In" such presses as" ordinarily constructed onlynarrow, or two-pagewide webs can be-used, and this ordinarily, requiresa separate paper feed ng and handling mechanism for each perfectingmechanism in the press; and therefore a large number of small web rollshave to be handled in publishing an edition ofany con-' siderable size.

The object'of the present inventionis to reduce the number ofpaper'feeding mechanisms required for such presses,"and lessen thenumber of web'rollsto be handled, by providing means whereby wide webscan be utilized, and the web Ican be fed fromsuch wideweb rollslitlongitudinally and the separate sections of such web respectivelydirected to separate printing mechanisms to be perfected, each web rollsupplyingtwo or more perfecting mechanisms. I

In accordance with the present invention each four page wide web-roll isarranged at one end of the press with the axis of the web roll parallelwith the plate and impression cylindersin the perfecting mechanisms; andmeans is provided for slittlng theweb longitudinally and one section ofthe slit web is led in a straight line directly to one of the perfectingmechanisms; while the other section of the web is diverted by means ofangle bars and led directly to another perfecting'mechanism; bothsections ofthe printed web being thereafter assembled at the folder inthe usualmanner'if desired. 1 H e rnnnmmwnefro rRINrIns-rmissns.

7 A four-page wide roll of web 'W may. be

I mounted -'ons1uitable supports, inthe usual -manner, at one end of thepress jandth'e web may b'efed from the roll in'the usual manner; as byfeed rolls 3, 3 The web roll 1V is soset that its aXis is parallelwiththeaxes "of the plate and impression cylin- I ders, and one end ofthe "web 'rollis in line with the ends 'of'the plate and impressioncylinders at; one side of the press; ;while the other-end ofthe web rollprojects "he yon'd'theends ofsuch plate and impression cylinders at'theoppo'site side of the press. The wideweb from-such roll may be led overany suitable; guides past 'aslitter I S,

operated in the usual manner, by whichthe web ,is divided into twolongitudinal sec tions-w' and 10 The section w'of-the web passesstraight from the web roll, past the slitter and over guides g g, to andbetween the plate and impression cyl nders in the printlng mechanism A;and thence over a guide 9 to the folder (not shown)'at the end of thepress t'or if desired to a second pri tingmechanis'm (not sh tbeirprmtedy 'lncolorsx I ,i

The section tutof the web'pas'ses-fronrthe V slitterS to and OYer aiguide g ,"then to and I I y over an angle bar 4 arranged at an angleof45 tothe web roll and plate and impresslon cylinders'b'y which thesection 20 is diverted 'w -is diverted back into a path'p'arallel with(and in the example shown above) the section a"; thence the section w'passes beyond the printingmechanism A to a guide g 'by which it isdirected to and between the plate and impression cylinders in theprinting mechanismB; thence it passes over a guide 9 to the folder '(notshown), or if desired to a second perfectingmechanism (not shown) to'beprinted in colors. v o r o will be seen that in this invention bothsections w, 'w of a wide web are preferably brought directly intoalinement; then each section of the web is passed toa separate printingmechanism; or mechanisms, which are preferably arranged parallel and ina strai-ght'line.

Theparti'cular printing mechanisms, or the numbeif of printingmechanisms through which the sections w, w of the web are led form no,part of the presentinvention.

By' this invention two or more narrow printing mechanisms, arranged inline, can

i be simultaneously supplied with sections of web from a single roll ofwide webarranged parallelwiththe axes of the cylinders in the printingmechanisms; and by this'invention one web, controlling and feedingmechawill sufiice to supply sections of web fronta wide roll todifferent alined printing mechanisms, ordinarily requiring two distinctnarrow web rolls and two feeding mechanisms to supply them with web.Inthe drawings the roll of WebVV is illustrated as beingfour pages wide,but of course itlmight be of any desired width, and be dividedinto anydesired number of longitudinal sections'-for example, if it is desiredtolprintaweb only one page wide in one, of the printing mechanisms thena web 'rollthree pages wide could be used and one section; instead ofbeing two pages wide could be one pagewide; therefore I do notconsidertheinvention restricted to the employment of webs an even numberof pages Wide; nor to having the web sections of the same, width.

What I claim is:

1. In a printing press. having a plurality of narrow printingmechanisms; means for supporting a roll of, web wider than theprintingmechanisms at one end of the press, one end of the web rollbeing'approxnnately in: line with the end of the printing mechanismatone side of the press, and the other end of the web roll projectingbeyond the other end of such printing mechanism; means for sllttlng theweb; means for d1- recting one section of the web direct from the webroll to one of the printing mechanisms; means for deflecting the othersection of the web between the web roll and the printing mechanism; andmeans for directing the diverted section of the web to the" otherprinting mechanism; substantially as described.

2. In a printing press having narrow rotary printing mechanisms; meansfor supporting a wide web roll at one endof the press; one end of theweb roll being approximately in line with the ends of plate andimpression cylinders in one printing 1nechanism, and the other end ofthe web roll projecting beyond the other ends of such cylinders;-meansfor slitting the'web means for directing-one section of the webstraightto the said printing mechanism; angle bars over which the other sectionof the web is 7 with the printing mechanisms, one end of' the-web rollbeing approximately in line with the ends of the printing mechanisms atone side of the press, and the otherend of the web roll projectingbeyond the other ends of the printing mechanisms at the opposite side ofthe press; meansfor slitting the web;means for directing one section of"the ,web straight from the web roll to one of-the printing mechanisms;means for defleeting the other section of the web between the web rollthe printing mechanismsjso as to bring such section of the web parallelwith the first section of the Web; and means for directingthe divertedsection ofthe web to the other printing mechanism; substantiallyasdescribed. p

4. In a printing press having two narrow rotary printing mechanismsarranged in line; nea'ns for supporting a wideweb roll at one end of thepress parallel with the plate and impression cylinders inthe printingmechanisms; one end of the web roll being approximately in line withtheends of the plate and impression cylinders at one side of the press, andthe other end of the Web roll projecting beyond the ends of thecylinders at the. opposite side of the press; means for slitting theweb; means for directing one section of the web straight to one of theprinting mechanisms; angle bars over which the other section-of the webis led and by which it is diverted into parallelism with the firstsection of the web; and

means for directing the second section of the Web after being sodiverted to another printing mechanism, substantially as described.

5. In combination a printing press having two two-page Wide rotaryprinting mechanisms arranged in line; and means for supporting afour-page Wide Web roll at one end of the press parallel with the plateand impression cylinders in the printing.- mechanisms, one end of theWeb roll being in line With the ends of the'plate andimpressioncylinders at one side of the press and the other end of the Web rollprojecting beyond the ends of the cylinders at the opposite side of thepress; With means for slitting the Web; means for directing one sectionof the Web straight to one ofthe printing mechanisms; a pair ofanglebars over Which the other section of the Web is led and by Which itis diverted into parallelism with the first section of the Web; andmeans for directing the second section of the Web, after being sodiverted, to the second printing mechanism, substantially as described.e

In testimony that I claim the foregoing as my own, I affix my signature.Y HENRY F. BEOHMAN.
